    摘要: Uncomfortable travel of a vehicle due to engine brake actions during the travel of the vehicle in traffic is prevented without using an one-way clutch within a transmission mechanism. An automatic transmission is composed of rotational elements that are braked at the time of establishing low stages, a brake that brakes the rotational elements, and control systems which control the oil pressure of the hydraulic servo in the brake. A band brake that creates differences in application forces, using self-energizing and deenergizing actions, serves as the brake, which is set to have an area in which the oil pressure during the drive is lower than the oil pressure during the non-drive, by setting the self-energizing direction as a direction of rotation of the rotational element during the drive and the deenergizing direction as an opposite direction of rotation of the rotational element during the non-drive. The control systems have a supplying mechanism which supplies oil to the hydraulic servo of the band brake at an oil pressure that is lower than the oil pressure during the non-drive and is equal to or higher than the oil pressure during the drive.

    摘要: An automatic transmission for five forward speeds equipped with a main transmission mechanism and an auxiliary transmission mechanism. The auxiliary transmission mechanism includes a multi-disc clutch and a hydraulic servo therefor arranged in a first planetary gear set. The first planetary gear set includes a first ring gear connected to an output unit of the main transmission mechanism and a first carrier connected to an output shaft and further to a first sun gear through a multi-disc clutch and a hydraulic servo for the former. The hydraulic servo for the multi-disc clutch is connected to an integral casing through a band brake and is arranged around the outer circumference of the hydraulic servo for the multi-disc clutch. A second planetary gear set is arranged on the hydraulic servo for the multi-disc clutch and includes a second ring gear connected to the output shaft, a second carrier connected to the integral casing through a multi-disc brake and a second sun gear connected to the first sun gear through the cylinder of a hydraulic servo for the multi-disc clutch. The rear casing forms part of the cylinder of the hydraulic servo for the multi-disc brake. The auxiliary transmission mechanism has a compact three-speed construction to provide five forward speeds in cooperation with the main transmission mechanism. The five-speed automatic transmission can be easily modified merely by removing the second planetary gear set and the brake for the 1st speed to provide a four-speed transmission at a reasonable cost due to the sharing of parts in common.

    摘要: An automatic transmission for a vehicle with a reverse gear brake that includes a case. A predetermined rotational element, having gear teeth and an axis, is disposed within the case. The predetermined rotational element only operates as a rotational element when achieving a reverse gear mode. A brake has a gear member. The gear member is attached to the case so that it cannot rotate relative to the case, but is movable along the axis of the predetermined rotational element so that it can be engaged and disengaged with the teeth of the predetermined rotational element. The predetermined rotational element is fixed to the case so that it cannot rotate relative to the case when the gear teeth engage the gear member.

    摘要: A 5-speed automatic transmission for a vehicle having a highly efficient top gear, a compact construction and a wide overall range of gear ratios. The automatic transmission has a speed changer which provides five gear stages, namely two speeds on the speed decreasing side and two speeds on the speed increasing side with a direct-coupled gear therebetween. The speed changer includes a ring gear connected to an output shaft, a first carrier, a first sun gear, a second carrier connected to the first carrier, a stepped pinion gear supported by these two carriers, and a sun gear meshing with the pinion gear. The first carrier is connected to an input shaft by a clutch and the first sun gear is connected to the input shaft by a clutch. The first sun gear may be stopped by a first brake, a second brake stops the second sun gear and a third brake is provided to stop a third sun gear. Top gear is achieved by meshing of the pinion gear with the second sun gear and the ring gear. Top gear is thus achieved with the equivalent of only one planetary gear set of intermeshing elements and without loss of efficiency. Also, the arrangement of the three planetary gear sets of the transmission is such that one planetary gear set can be easily removed to make a 4-speed transmission derived from the 5-speed transmission of the invention.

The hydraulic servo device includes a cylinder, a piston position to slide within the cylinder, a rod connected to the piston, and a cover member for closing the open end of the cylinder. The cover member, in association with the cylinder and the piston, defines an oil chamber in the cylinder. An oil passage for feeding an oil pressure to the oil chamber is formed by an opening in the cover member.

    摘要: An automatic transmission is configured to achieve at least ten forward speeds and one reverse speeds. This is achieved through the use of two planetary gear sets with a plurality of clutches and brakes configured to operably couple different components of the two planetary gears to achieve different speeds. For example, operation of a first clutch inputs decelerated rotation of a reduction planetary gear to a third sun gear. Operation of a second clutch transmits from an input shaft to a third ring gear, a third clutch inputs decelerated rotation of the reduction planetary gear to the second sun gear, a fourth clutch transmits from the input shaft to the second carrier, a first brake prevents a second sun gear from rotating, a second brake prevents a carrier from rotating, a third brake capable prevents a third ring gear from rotating.

    摘要: A first planetary gear unit PR and a clutch C3 for outputting reduced speed rotation are located on one axial side of a second planetary gear unit PU, and a clutch C1 for connecting and disconnecting an input shaft 2 to/from a sun gear S2 and a clutch C2 for connecting and disconnecting the input shaft 2 input to/from a carrier CR2 are located on the other axial side of the second planetary gear unit PU. An output mechanism is located between the first and second planetary gear units. As compared with a drivetrain wherein the clutch C1 or clutch C2 is located between the two planetary gear units, the two planetary gear units can be located closer together, and a transmitting member that transmits the reduced speed rotation can be made shorter. Further, compared to a drivetrain wherein the clutches C1, C2, C3 are located together on one axial side, the oil supply to the hydraulic servos can be simplified.
